Cupric reducing antioxidant capacity

CUPric Reducing Antioxidant Capacity (CUPRAC) assay... 

The cupric reducing antioxidant capacity (CUPRAC) method [82], which involves the use of copper(II)-neocuproine reagent, has been modified to assay both lipophilic and hydrophilic antioxidants simultaneously, including PG and DG [83]. The modification makes use of methyl-P-cyclodextrin, which forms inclusion complexes, increasing the solubility of lipophilic antioxidants and avoiding the turbidity of alcohol-water solutions.
